Which of these explains which store has a better buy? store c, because the ratio of the number to the cost is 6: 1 in store c and 7: 1 in store d. store c, because the ratio of the number to the cost is 1: 6 in store c and 1: 7 in store d. store d, because the ratio of the number to the cost is 2: 14 in store c and 3: 24 in store d. store d, because the ratio of the number to the cost is 14: 2 in store c and 24: 3 in store d.

a) justify

step-by-step explanation:

justifying is just part of everyday life. justify kind of means proof so i think the answer is a) justify.

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
